210 EPHESTIA PAbSULELLA. 



By the beginning of April, 1882, they, however, 

 began again to show themselves and were grown 

 considerably, and yet required a further supply of their 

 food, as by this time a prodigious quantity of frass 

 had been made. 



The first specimen of the perfect insect was bred on 

 the last day of April ; others followed on the 12th of 

 May, others again on the 1st and 4th of June, and the 

 last on the 14th of July. 



The egg of Ephestia passulella is elliptical in shape, 

 with bluntly rounded ends, and finely pitted surface, 

 whitish at first and soon of a delicate straw-yellow ;. 

 two days before hatching it assumes an ochreous 

 tinge, and the next morning a light brown spot 

 appears at one end, and within a few hours the larva 

 is hatched. 



At first the young larva is of a whitish-ochreous 

 tint, with a brown shining head and very narrow plate 

 across the second segment, and when nearly a month 

 old has a faint tinge of reddish, or pinkish-brown, 

 with the head very dark brown and the plate still 

 narrow, but at this time with very little more colour 

 than the body. 



At the age of three months the body is of a light 

 brownish-pink colour, with reddish-brown head, and 

 a blackish-brown plate on the second segment, and 

 another on the anal flap, and there is a pinkish-brown 

 dorsal line showing very faintly ; the minute tubercular 

 shining brown dots can be very well discerned. 



When full-grown the larva measures 10 mm. in 

 length, and is of moderately slender proportions, 

 cylindrical, though tapering very slightly at each end, 

 the segments having a subdividing wrinkle across the 

 middle of each, and the legs are much under the body ;. 

 in colour the head is reddish-brown, and glossy, and 

 it has a margin of pale skin in front of the shining 

 black and brown neck-plate, which is dorsally divided 

 with a line of the pallid ground colour of the thoracic 

 segments, and beyond them this ground colour imper-
